Objective: Use the supplied reference image of the person to generate a professional, technical character reference sheet. The output must exactly match the subject's identity, realism, textures, and overall aesthetic. Layout: Present on a solid, neutral gray background in two horizontal rows. Top Row: Four full-body A-pose views in this order: front, left profile, right profile, and back. Bottom Row: Three detailed headshot portraits aligned beneath the top row: front, left profile, and right profile. Technical Specs: Maintain identical character features, consistent scale, and perfect head-height alignment across all seven panels. Use flat, uniform studio lighting to preserve detail in the shadows. Ensure a clean, symmetrical silhouette with sharp rendering, crisp edges, and print-ready, high-fidelity details.
